Prevalence of non-IP devices across Industrial IOT

“By 2020, 90% of Internet of Things (IoT) projects will

utilize an IoT gateway, up from 60% today.”

- Gartner, Explore the Roles of IoT Gateways in Five Edge Use Cases, 16 June 2017


Gateway ManagementUptime, Uptime, Uptime!

Factory automation• Gateways provide local execution

• Online & offline operation

• Equipment can shut down, stopping factory lines

• Emergency situations, could require hard real-time control to stop

Critical requirements• Accurate, detailed, & timely error reporting

• Ability to react and respond

- Automation

- Quick recovery from failure


Edge Compute

Not all data can or needs to go to cloud

• Latency

• Offline operation

• Simplification

• Data conservation

Introducing Mbed Edge – protocol translationProvided as SDK for gateway OEMs to integrate into their hardware/software platform


Key components of Mbed Edge protocol translation

Mbed Cloud• Gateway device type in cloud device registration

Mbed Edge core• Gateway to proxy for protocol

• Gateway endpoint device

Legacy protocol translator & control• Manage and controls legacy devices connected

Firmware update• Update Mbed Cloud firmware

Mbed Edge protocol translation

Mbed Edge• Security between gateway and Mbed Cloud

• Reporting of any errors in either the protocol translation interface to the legacy interface or connection to Mbed Cloud

• Maintaining & reporting status of connectivity to Mbed Cloud

Partner (Gateway developer)• Onboard and pairing of legacy devices to the gateway legacy interface (e.g. BLE, Zigbee, Modbus)

• Protocol interface implementation between legacy interface and Mbed Edge

• Monitoring status of protocol translation interface and connectivity to Mbed Cloud, including error reporting to the cloud (arm provides example)

• Offline control and management of legacy interface in the event of loss of connectivity to Mbed Cloud

• Factory provision keys into the gateway

Working together: Partner and Arm responsibilities


Mbed Edge protocol translation

Mbed Partner* availability: Q4’2017

Available in source code

API Format

• Protocol translation: ‘C’

• mbed cloud status: REST (http)

Hardware reference design:

• Qualcomm IPQ4029 (OpenWRT)

• Advantech WISE-3610 - LoRA

If not already, join Arm Mbed Partner Program

Review protocol translation API

Download* Mbed Edge source & integrate onto your gateway platform

Write necessary code to bridge non-IP endpoints using Mbed Edge translation protocol translation API

Call to actionDeliverables

* Available in Q4’2017, watch for partner newsletter

How to get started:


Mbed Edge gateway management & edge compute componentsEdgeJS APIs

• Device normalization, control, events, on-boarding

• Alarming is a major IoT use case: Raise & lowerApplication specific alarming -customizable

• Subscribe to device events, take action

Protocol & Device Support

• Built-in: BACnet, modbus, ZigBee, Z-Wave, Bluetooth, UPnP, others

• Extensible. Vendors / customers can add their own support.

• Device controllers can be dynamically updated from the cloud.

EdgeDB

• Distributed database for gateways

• Allows storage to be shared across all gateways in a site

• Storage is local, works if cloud is down, syncs when cloud up

• Enables local edge computing across a “site”

EdgeJS Apps

• Control, listen, take action on devices locally without cloud

• Apps run across all gateways in the “site”

• Containers & Multi-tenancy – apps are protected from each other

• Cross-platform


Mbed Edge gateway management & edge compute

Gateway ManagementLarge scale management. Status, backup & restore, configurations, logging and remote access

Edge App & Device Support DeploymentDeploy new edge applications (secure docker containers), new device controller components, configure, rollback, etc.

Dashboard & monitoring APIs, AlarmingDeploy, manage & maintain many gateways, watch & monitor for custom alarms across many sites

Roles & Permissions Assign user roles across sites, determine device access.

Mobile Support Users can control & monitor devices.


Porting Mbed Edge enhanced stack onto new hardwareComplete Port

• Entire Linux OS system with all components

• Standard Linux OS kernel

• All systems management capabilities

• Radio support is the majority of time / cost

• Known, tested system. Full support

• Kernel patches and drivers for OEM hardware will be merged into the kernel, and Linux OS kernel for the OEM HW is provided

Component Port

• Key components port: Full protocol support (given that radios can be supported)

• Time must be spent understanding & potentially updating / patching portions of the OEM’s existing BSP

• Support will be limited


Mbed Edge Portal Key Capabilities

• Manages geographically dispersed gateways

• Sites: allow multiple gateways to share data redundant, durable.

• Full systems management: web UI control, logging, console if required

• Purpose built for IoT (compare this to solutions meant for servers which are re-purposed for gateways)

• Provides insight down to the end-device level

• Deploy IoT scripts fast using EdgeJS containers
